Each particle/granule of carbon provides a large surface area/pore structure, allowing contaminants the maximum possible exposure to the active sites within the filter media. One pound (450 g) of activated carbon contains a surface area of approximately 100 acres (40 Hectares). Activated carbon works via a process called adsorption, whereby pollutant molecules in the fluid to be treated are trapped inside the pore structure of the carbon substrate. Carbon filtering is commonly used for water purification, in air purifiers and industrial gas processing, for example the removal of siloxanes and hydrogen sulfide from biogas.

It is also used in a number of other applications, including respirator masks, the purification of sugarcane and in the recovery of precious metals, especially gold.
Indoor Air Quality - Improving Indoor Air Quality. You may be surprised to know that even indoor air can be polluted, sometimes more so than outdoor air.

And because many people who have COPD or other chronic health conditions spend a great deal of time indoors, improving indoor air quality is especially important. To help you improve the quality of your indoor air, here are 11 steps designed for those with COPD or other chronic illnesses.
How to Grow Fresh Air. How to Remove Fluoride from Drinking Water. Most people are aware that there is a controversy surrounding public fluoridation of drinking water.

Here is a list of ways to obtain drinking water without fluoride. In addition, I've listed water purification methods which do not remove fluoride from water. Ways to Remove Fluoride from Water Reverse Osmosis Filtration This is used to purify several types of bottled water (not all), so some bottled waters are unfluoridated. Reverse osmosis systems are generally unaffordable for personal use.
